Chest Pain Assessment for Nurses
Chest pain is one of the most common and potentially life-threatening complaints nurses encounter. Systematic assessment — differentiating cardiac from non-cardiac causes and identifying red flags — determines urgency and guides immediate action.

OPQRST Pain Assessment Framework
OPQRST provides a systematic structure for characterizing chest pain. Each component yields diagnostic information about etiology and severity.
O
OnsetQuestions to ask:
- “When did the pain start?”
- “What were you doing when it began?”
- “Did it start suddenly or gradually?”
Clinical interpretation: Sudden onset ('tearing' or 'ripping') → aortic dissection. Onset with exertion → angina or ACS. Onset with deep breath → pleuritic (PE, pleuritis).
P
Provocation / PalliationQuestions to ask:
- “What makes the pain better?”
- “What makes it worse?”
- “Exertion, rest, breathing, position, food?”
Clinical interpretation: Worsens with exertion, relieved by rest → stable angina. Occurs at rest → unstable angina or ACS. Worsens lying flat, improves leaning forward → pericarditis. Relieved by antacids → GERD.
Q
QualityQuestions to ask:
- “Describe the pain in your own words.”
- “Is it pressure, squeezing, sharp, burning, tearing, aching?”
Clinical interpretation: Pressure/squeezing/heaviness → cardiac ischemia. Sharp/pleuritic → PE, pleuritis, musculoskeletal. Tearing/ripping → aortic dissection. Burning → GERD or esophageal.
R
RadiationQuestions to ask:
- “Does the pain move anywhere else?”
- “Arm, jaw, neck, back, shoulder, abdomen?”
Clinical interpretation: Radiation to left arm or jaw → classic ACS. Radiation to back between scapulae → aortic dissection. Radiation to right shoulder → biliary/diaphragmatic. No radiation → less suggestive of cardiac (but ACS can be non-radiating).
S
SeverityQuestions to ask:
- “On a scale of 0–10, how bad is the pain?”
- “How does it compare to prior episodes?”
Clinical interpretation: Severity does not reliably predict etiology — some AMI patients report mild discomfort. Track serial severity to assess response to treatment. Sudden 10/10 'worst pain ever' → consider aortic dissection.
T
Time / DurationQuestions to ask:
- “How long have you had this pain?”
- “Is it constant or does it come and go?”
- “Has it changed since it started?”
Clinical interpretation: Angina typically <20 minutes and resolves with rest/NTG. AMI pain >20–30 minutes and persistent. Pleuritic pain may be intermittent with breathing. Aortic dissection is typically sudden, severe, and continuous.
Red Flag Findings — Escalate Immediately
Any of these findings require immediate provider notification and emergency action
- !ST elevation or new LBBB on 12-lead ECG
- !Hemodynamic instability: hypotension (SBP <90), tachycardia, diaphoresis, altered mental status
- !Tearing or ripping chest pain radiating to the back — aortic dissection until proven otherwise
- !Sudden severe dyspnea, unilateral leg swelling, pleuritic pain — pulmonary embolism
- !Pulsus paradoxus, muffled heart sounds, JVD — cardiac tamponade
- !Unequal blood pressure between arms — aortic dissection
- !New murmur in the setting of chest pain — papillary muscle rupture, aortic dissection
- !Chest pain with syncope or near-syncope
- !SpO₂ <90% or rapidly declining
Cardiac vs Non-Cardiac Chest Pain
| Feature | Cardiac (Ischemic) | Non-Cardiac |
|---|---|---|
| Quality | Pressure, squeezing, heaviness, tightness | Sharp, stabbing, burning, pleuritic |
| Location | Substernal, diffuse | Localized, reproducible with palpation (MSK), epigastric (GERD) |
| Radiation | Left arm, jaw, neck, back | No radiation, or localized area |
| Provocation | Exertion, emotional stress, cold; rest pain in ACS | Deep breathing (PE, pleuritis), position (pericarditis), swallowing (esophageal), palpation (MSK) |
| Relief | Rest (stable angina); NTG partial in ACS | Antacids (GERD); leaning forward (pericarditis); NSAIDs (MSK, pericarditis) |
| Associated sx | Diaphoresis, dyspnea, nausea, syncope | Cough, fever (pleuritis); heartburn (GERD); anxiety/hyperventilation (panic) |
| Duration | >20 min persistent = ACS | Often varies with breathing, position, or activity |
Important: Atypical presentations are common — women, elderly, and diabetics frequently lack classic ischemic features. Treat all chest pain as potentially serious until proven otherwise.
Associated Symptoms and Clinical Significance
| Symptom | Clinical Significance |
|---|---|
| Diaphoresis (sweating) | Highly suggestive of cardiac ischemia — sympathetic nervous system activation from myocardial ischemia |
| Dyspnea | ACS, pulmonary edema, PE, tension pneumothorax; can be primary ACS symptom especially in women and elderly |
| Nausea / vomiting | Common in inferior MI (vagal activation from RCA distribution); also aortic dissection and shock |
| Syncope | Hemodynamic compromise, lethal arrhythmia, aortic dissection, cardiac tamponade — always serious |
| Palpitations | Arrhythmia — may precede or accompany ACS; atrial fibrillation common post-MI |
| Fever / chills | Suggests infectious etiology: pneumonia, pericarditis, myocarditis, pleuritis |
| Cough / hemoptysis | PE (hemoptysis), pulmonary edema from CHF (pink frothy sputum), pneumonia |
| Unilateral leg swelling | Deep vein thrombosis → consider pulmonary embolism as etiology of chest pain |
Emergency Response Priorities
1
Stay with the patientDo not leave a patient with active chest pain unattended. Continuous monitoring is essential.
2
Notify provider immediatelyUse SBAR for clear, concise communication. State vitals, symptom onset, character, and associated findings.
3
Obtain 12-lead ECG within 10 minutesFor any new chest pain. ST elevation activates STEMI protocol without waiting for labs.
4
Establish IV access and draw labsLarge-bore IV × 2. Stat troponin, BMP, CBC, PT/INR. Serial troponins as ordered.
5
Apply continuous monitoringCardiac monitor, pulse oximetry. Supplemental O₂ only if SpO₂ <90%.
6
Administer medications per orderAspirin 325 mg chewed (first drug). NTG sublingual for ongoing chest pain (contraindicated in inferior MI with RV involvement, SBP <90, or PDE-5 inhibitor use).
7
Frequent reassessmentReassess pain every 5–15 minutes. Report persistent or worsening pain, new ECG changes, or hemodynamic deterioration.
Documentation Considerations
Document in real time and include:
- ›Exact time of patient report and time of nurse assessment
- ›Full OPQRST characterization of pain including severity scale
- ›Associated symptoms present or absent (ROS: dyspnea, nausea, diaphoresis, syncope, palpitations)
- ›Vital signs including bilateral BP if aortic dissection suspected
- ›Time 12-lead ECG obtained and who was notified
- ›Provider notification time, name, and orders received
- ›Medications administered, dose, route, and patient response
- ›Pain reassessment rating after interventions
- ›Any change in condition, hemodynamic status, or rhythm
NCLEX Pearls
- ›First action for any new chest pain: 12-lead ECG within 10 minutes — before waiting for labs.
- ›Diaphoresis with chest pain is a highly significant cardiac red flag — always escalate.
- ›OPQRST systematically characterizes pain — character, radiation, and associated symptoms are most diagnostically useful.
- ›Tearing/ripping pain radiating to the back = aortic dissection until ruled out — check bilateral BPs.
- ›Leaning forward relieves pericarditis pain — a classic NCLEX distinguishing feature.
- ›Women, elderly, and diabetics often present atypically — fatigue, dyspnea, jaw pain without classic chest pressure.
- ›Nitroglycerin is contraindicated if: BP <90/60, inferior MI with RV involvement suspected, or PDE-5 inhibitor use within 24–48 hours.
